So a small but interesting device I did not expect for the price. I have the latest firmware previously downloaded (Comag.tv) and then installed on a USB stick (was easy and only took a few seconds). The receiver is now running a few days without errors and there are only positive to report. The picture is excellent in both broadcasts in SD (upscaling) as well as HD broadcasts. The operation is very easy by hand, as the menus are well organized and give no mystery. EPG, PVR (with 16GB flash drive from Transcend) and teletext function also problem-free. The handy remote control also like it very much. Previously had a Technisat receivers (Digit 5 S), which was hanging on a regular basis. Time went the EPG, sometimes not ... crunched the remote control, paint was peeling off (and at this price!). Bin 40 very happy with the Comag SL.
